A precision wheel torque and weight transducer for most common agricultural tractors.

摘要

A precision wheel torque and weight transducer for most common agricultural tractors was developed at King Saud University, Riyadh, Saudi Arabia. The standard wheel centre of an MF 3090 (Massey Ferguson 3090) tractor was replaced with the developedwheel torque transducer to measure the torque and forces acting on the tractor wheel. The wheel torque and weight transducer incorporated 3 load sensing clevis bolts. Its force measurement on the revolving wheel combined with the measurement of angular position of the wheel by a position transducer (shaft encoder) was used to determine the total horizontal and vertical components of forces. The construction, instrumentation and calibration of the wheel torque and weight transducer is described.
